3D Reconstructions and more

[Malcolm Herbert <SM005@xxxxxxxxxxxxxx>]

Hello all...

I am a new subscriber to Paleonet, so first a little background

I am primarily a computer scientest, but have spent the last 3-4 years 
working computer-based 3D reconstructions from serial sections in 
palaeontology. This work has been mainly with Brachiopods, in conjunction
with Mike Basset at the National Museum of Wales, Cardiff. 

Some reconstructions and further details can be found at my web page

On the 3D reconstruction issue a number of points

1. Most serial sections do not contain fiduciary marks and therefore
cannot be aligned accurately in 3D

2. The sections are usually undersampled and the rate of change in shape
is usually dramatic making reconstruction difficult

3. Section drawings can sometimes by


e difficult to convert into digital data


this tends to make most current data and drawings unsuitable for 
reconstruction and the results can sometimes be dissappointing

If you want any more information please di hestitate to contact me
